	Depends on the press.  Some presses have a dual threaded 
	design.  The coarse thread for speed and the fine for
	pressure.  The the fine and coarse threads are cut over
	one another on the screw and the nut is split such that
	there is a coarse and fine threaded portion that can be
	selectively engaged according to need.

	Other presses have but one thread.  I don't know if there
	are any other configurations, these are the two I have seen.
